Medicare is a sort of health insurance developed by the U.S. government for senior citizens, along with people who have specific disabilities and sicknesses. If someone that has Medicare needs rehabilitation for instances of drug or alcohol abuse, their treatment will either be covered entirely by their Medicare insurance or to a significant degree. The only exception is, the person will have to acquire treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the person will be allowed to start rehab, they may also have to see their primary care physician who must declare that rehab services are medically necessary, and the physician will usually approve what type of treatment the individual will take part in. Medicare Part An and Part B cover a variety of treatment providers. Medicare Part A covers an inpatient stay in a Medicare accepted program if the individual has to be in a hospital for problem, as well as the costs that they will have to cover personally are identical to any other hospital stay. Medicare Part B will partially cover outpatient rehab in a Medicare accepted program, and the individual will have to cover whatever Medicare Part B doesn't pay for with supplement insurance coverage or they will have to self pay.
